Splunk is an American multinational corporation based in San Francisco, California, that produces software for searching, monitoring, and analyzing machine-generated big data, via a web-style interface.[1]

Splunk (the product) captures, indexes and correlates real-time data in a searchable repository from which it can generate graphs, reports, alerts, dashboards and visualizations.[2][3]

Splunk has a mission of making machine data accessible across an organization by identifying data patterns,[4] providing metrics, diagnosing problems and providing intelligence for business operations. Splunk is a horizontal technology used for application management, security and compliance, as well as business and web analytics.[1] As of early 2015, Splunk has over 9,000 customers worldwide.

Splunk is based in San Francisco, with regional operations across Europe, the Middle East, Africa and Asia, and has over 1700 employees.


The company was started in 2003 by co-founders Michael Baum, Rob Das and Erik Swan.[5]

Splunk was backed by venture firms August Capital and JK&B Capital. By 2007, Splunk raised 40 million USD [6] and became profitable in 2009.[7] In 2012, Splunk had its initial public offering, trading under NASDAQ symbol SPLK.

In September 2013, the company acquired Bugsense, a mobile-device data-analytics company.[8] Bugsense is a mobile analytics platform used by developers to improve app performance and improve quality. It provided a software developer kit, to give developers access to data analytics from mobile devices that it managed from its scalable cloud platform.[9] The acquisition amount is undisclosed.

In July 2015, Splunk acquired Caspida, a cybersecurity startup, for $190 million.[10]

In October 2015, Splunk sealed a "cybersecurity alliance" with U.S. government security contractor Booz Allen Hamilton Inc. to offer combined cyberthreat detection and intelligence analysis technology.[11]


Splunk offers products that perform real-time and historical search, as well as reports and statistical analysis. The product can index structured or unstructured textual machine-generated data. Search and analytics operations are specified using Search Processing Language, created for managing machine-generated big data. Originally based upon Unix Piping and SQL, its scope includes data searching, filtering, modification, manipulation, insertion, and deletion.

In 2011, Splunk released Splunk Storm, a cloud-based version of the core Splunk product. Splunk Storm offers a turnkey, managed and hosted service for machine data.[12] In 2013, Splunk announced that Splunk Storm would become a completely free service and expanded its cloud offering with Splunk Cloud.[13]

In 2013, Splunk announced a product called Hunk: Splunk Analytics for Hadoop, which supports accessing, searching, and reporting on external data sets located in Hadoop from a Splunk interface.[14]

In 2015, Splunk announced a Light version of the core Splunk product, aimed at smaller IT-environments and mid-sized enterprises.[15]


Splunk offers its main software in two license types: an enterprise license designed for companies and large organizations, and a freeware license designed for personal use.[16][17] The freeware version is limited to 500 MB of data a day, and lacks some features of the Enterprise license edition. Next to these two licenses, a separate version is offered, dubbed Splunk Light, which is directed at small IT environments and has a 20GB daily data limit, a maximum of 5 users and is a single-server solution.[18]

As of the release of Splunk Cloud, Splunk Storm is free and includes 20GB of data storage.[19]


Splunk was designed for use in information technology operations; it is also used in other ways.[20] Users in IT operations include Sony,[21] Metropcs,[22] Ceryx,[23] and Denver Water.[24] Cars.com,[25][26] Domino's Pizza,[27] and National Public Radio[28] are among those who use it for web analytics. In the Internet of Things it is used by the Bangkok Metropolitan Administration Department of Drainage and Sewage to send alerts,[29] by Eglin Air Force Base for energy conservation,[30] by Nest Labs to analyze thermostat data,[citation needed] by iRhythm to check on product performance[citation needed] and by an elevator company to monitor elevator usage.[31] In computer security the University of Connecticut[32] and federal and state agencies use the technology.[33] It is used to help with regulatory compliance by Barclays bank,[34][35] Credit Suisse,[citation needed] Monster.com,[36] and Sportsbet.com.au.[37]
